Reasons to Restore iPhone from DFU Mode

You can try an in-depth reset when a regular restore cannot fix your situation and bring your iPhone back to life. The iRemove team has prepared a guide on how to restore the iPhone from DFU mode via iTunes or Finder. Follow it step-by-step to completely erase your smartphone and reload its hardware and software control.

Before we explain why you need to use iPhone DFU restore, it is a must to tell you more about this term. DFU stands for Device Firmware Upgrade. It is a special mode that helps restore any iPhone from any possible state.

Through DFU, your BootROM accepts iBSS, and it can accept APTicket if you own an A7+ smartphone. The thing is, your Device Firmware Upgrade is a SecureROM's part. You cannot remove it because it is burned into your iPhone hardware.

Restore DFU iPhone 8, 8 Plus, X, SE (2nd Gen)

Find your USB to Lightning cable and a working computer. Ensure that your Windows PC or Mac running Mojave or an earlier version than macOS 10.14 has the most recent iTunes. If you have a computer with macOS 10.15 (Catalina) or newer, you will use Finder.

1. With your iPhone 8, X, or newer version, connect to Mac or PC, launch iTunes or Finder.
2. Click once your Volume Up on the smartphone. Then click once your Volume Down button.
3. Click-hold the Side button. Do so and watch how the display becomes black.
4. With a black screen, you should keep holding your Side button and press-hold the Volume Down button for approximately five seconds.
5. Let go of only the Side button but still keep pressing Volume Down. Release it when your smartphone is visible in iTunes or Finder.
6. Restore DFU iPhone 8 or newer Apple handset.

DFU Restore iPhone 7 and 7 Plus

Use your computer, Mac Mojave or older Apple computer or Windows PC, a USB to Lightning cable, and the most recent iTunes. Work with Finder instead of iTunes if you have Mac Catalina or a most recent macOS device.

1. After your iPhone 7/7 Plus (powered on or off) is connected to a computer, launch iTunes or Finder.
2. Press these two buttons at once (hold them too), Power (Sleep/Wake) + Volume Down.
3. After counting to eight, release only the Power (Sleep/Wake) button while still pressing the Volume Down.
4. When your iTunes or Finder shows the iPhone, you can let go of Volume Down. The phone screen must be black. Only when it is dark, have you successfully entered DFU. If you see the Apple logo on your handset screen or iTunes asks you to connect your smartphone, you should repeat all the steps.
5. Once in DFU, restore iPhone 7 or 7 Plus.

DFU恢复iPhone 6S，6，SE（第一代），和以前的版本

你将需要一台电脑（Mac或PC），一条Lightning转USB的电缆，以及iTunes软件。产品将适用于所有Windows电脑和macOS Mojave（或更老的）Mac。Catalina Macs的拥有者将使用Finder而不是iTunes（其工作原理类似）。

1. 一旦你把你的iPhone 6S, 6, SE（第一代）连接到你的电脑，就启动iTunes。请注意，你的iPhone可以打开或关闭（现在并不重要）。
2. 你必须同时按住两个按钮，原点+侧面（开/关/锁）。数到8，然后放开侧面（开/关/锁），同时仍按住原点。
3. 只有在iTunes（或Finder）显示你的智能手机时才松开Home键。一旦iPhone进入DFU模式时，产品的屏幕必须是黑色的，没有标志。因此，如果你看到一个标志或显示屏不是黑色的，你是不成功的。按照上面的指示来解决这个问题。
4. 进入DFU后，恢复你的iPhone 6S，SE（第一代），6。

请注意!假设iTunes或Finder从DFU模式恢复你的iPhone需要超过15分钟，而你的智能手机自己退出了设备固件升级。那么，你必须再次重复上面的步骤。这是一个必须进入DFU模式，并尝试从头开始DFU恢复。

请记住，在某些情况下，组件损坏的iPhone可能无法成功完成DFU恢复。如果你有一个损坏的设备，进入DFU模式会破坏产品。
